Reliability analysis of an automotive transmission system

Abstract

The complexity of vehicles and equipment in present day defence services is growing considerably, and the importance of equipment availability as a prime battle-winning factor for the defence services cannot be overemphasized. In defence services the reliability in totality of an automotive system such as a battle tank, troop carrier, etc. is essential to meet the inescapable warlike requirements. It is not in the interest of any fighting force to go into operation with the slightest doubt about the performance of the equipment. To keep the warlike equipment/vehicles rolling, all subsystems need to be in serviceable condition in all types of terrain. One of the most essential subsystems whose reliability cannot be compromised at any stage is the transmission system. In the present paper a reliability analysis of an automotive transmission system of the general service type of vehicle being used by the Indian Army is reported. The complete transmission system has been subdivided into 12 subsystems and maintenance policies for these 12 subsystems have also been suggested.
